Application filed November 26, 1915. SerialNo. 63,574.

- of Michigan, have invented certain new and useful Improvements in Mattresses or the like, of which the following is a specification.

kThis invention relates to mattresses or the li e.

@ne object is to provide a soft, light, hollow, mattress with a minimum amount of hair or other upholstering material and which provides for a free and easy longitudinal rocking movement under the action of the user.

Another object resides in the provision of a soft, resilient and luxurious mattress for beds or the like capable of giving a very quieting and comfortable effect, and which is not liable to settle or get lumpy and which is easily and readily ventilated and dried in the event of dampness.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion and minor details without departing from the spirit or sacrificing any of the advantages of the invention.

1n the drawings :lBigure 1 is a top plan view of the invention partly broken away at one corner to illustrate the interior of the mattress. Fig. 2 is an enlarged longitudinal sectional view. Fig. 3 is a detail perspective view of one of the coiled springs. Fig. A is an enlarged detail fragmentary view of a set of alining coiled springs constructed in accordance with my invention and fitted within pockets of the inclosing sack therefor. Fig. 5 is a side elevation of aspring having a flat band connected thereto.

The mattress A, as illustrated in the accompanying drawings, embodies the usual covering 10 of ticking or other suitable material. A lining 11 is arranged within the covering in spaced relation thereto, forming an interspace which is filled with hair, cotton or other suitable upholstering material, the top and bottom of the covering and adjacent faces of the lining being tufted by in a particular way.

threads or otherwise, the same passing entirely through the upholstering material 12.

The mattress is filled with springs B which render the mattress pliable and more or less hollow, and light and providing a. comparatively inexpensive mattress, reducing the amount of hair or other upholstering material required to a minimum.

The springs B are preferably long and arranged side by side either longitudinally or transversely of the mattress but preferably longitudinally thereof. Each spring is preferably alike and of the coiled type, taking preferably a rectangular formation and formed so that they yield in the direction of their length and preferably in one direction only. The rectangular formation of the springs practically completely fills the interior space of the mattress and obviates depressions or uneven supporting spaces. As shown, each spring includes base portions 13 arranged in parallel relation in a direction preferably slightly inclined with the opposite side parts 14 and 15 inclined in the same direction with relation to each other but with the side parts 14 inclined to a greater extent than the side parts 15. The

tit)

top parts 16 of each spring are inclined and substantially parallel with relation to each other.

By reason of forming my spring as described above, a substantial bearing surface is provided at the base thereof, while the top portion thereof is rendered very flexible and yet allows an even movement of each convolution of the spring in a lateral direction.

While the springs are arranged side by side, they are preferably spaced slightly from each other and this spacing is effected For instance, the springs are confined within pockets 17 formed in an inclosing sack 18. This sack is preferably formed of canvas or other suitable material and has partitions of the same material as the sack which form said pockets and are sewed to the sack with the ends of each spring preferably overlapped by the ends of said partitions and prefer ably overlapped by the top and end portions of the sack, the overlapped portions being preferably sewed together. The remaining coils of the springs are free of the partitions or the sack proper.

By virtue of the partitions interposed between the alining springs the springs are wise.

not permitted to rub against each other and i make a noise. These partitions also serve to prevent twisting or other dis lacement of the springs, maintaining them in close alining relation and yet preventing rubbing together of the springs.

The sack with or without the springs contained therein may be easily inserted through one. end of the ticking and theend of the latter closed by sewing or other- To make repairs, if necessary, one end of the ticking may be opened and any one of the springs may be withdrawn from its pocket or the sack with all'the springs may be withdrawn.

A long flat steel spring band 19 may be secured to each spring, if desired. When employed, the band extends entirely along the bottom or other side of the coiled spring and has its ends secured to the top or opposite side of the spring by means of suitable clips 20, there being suitable clips 21 for securing the body of the steel band 19 to the spring B. This band spring 19 serves to. hold the spring B from twisting or in any other way getting out of shape and when these band springs 19 are employed the mattress is rendered more pliable on one side than on the other, producing what may be termed a double mattress, one side soft and the other side relatively hard, the side of the mattress on which the bands 19 are disposed producing less resiliency than the other side.

What is claimed is:

1. As a new article of manufacture, a coiled rectangular shaped spring whose top and bottom portions are arranged normally in parallel planes inclined in opposite directions across the longitudinal axis of the spring and whose side portions are inclined slightly from the vertical, all in the same direction, the parts on one side being inclined to a greater extent than the similar parts on the other side, thereby providinga series of square loops formed of one continuous piece of wire, drawn out along the axis of the loops to form a tubular structure of square cross section.

2. As a new article of manufacture, a coiled rectangular shaped spring whose bottom portions are arranged normally in parallel planes and whose side portions are inclined in the same direction from the Vertical, the inclined parts on one side being inclined to a greater extent than the similar parts on the other side and the top parts all being parallel to each other and helically inclined to the axis of the spring, and a band spring connected to the aforesaid spring and connected at its ends to the ends of the aforesaid spring.

3. A mattress comprising a ticking provided with a central recess, a plurality of rectangular shaped spiral springs disposed lengthwise in said recess, longitudinally of the mattress, said springs composed of inclined loops adapted to yield laterally when subjected to pressure.

4. A mattress comprising a ticking provided with a central recess, a sack disposed in said recess, a plurality of rectangular shaped spiral springs disposed lengthwise in the sack, longitudinally of the mattress, said springs composed of inclined loops adapted to yield laterally when subjected to pressure.

5. A mattress comprising a ticking provided with a central recess, a sack disposed in said recess and having a plurality of longitudinally disposed alining pockets, and rectangular shaped spiral springs disposed lengthwise in said pockets, longitudinally of the mattress said springs composed of inclined loops adapted to yield laterally when subjected .to pressure.

6. A mattress comprising a ticking provided with a central recess, a plurality of rectangular shaped spiral springs disposed lengthwise in said recess, longitudinally of the mattress, said springs composed of inclined [loops adapted to yield laterally when subjected to pressure, and a band spring substantially the length of the spiral springs, having its ends secured to opposite ends of said spiral springs.

In testimony whereof I aflix my signature in the presence of two witnesses.
